Hello!

I would say that the way to do this is to grab the Task ID from your Flexi, store it, and have a "state" in your workflow that will resend - with state selected from the outside manually, maybe due to a status. 

There is a "Store Task ID" option in the FlexiTask.. assign to a variable. 

Then in a notification, do this for the URL:   {Common:WebURL}/Lists/Workflow Tasks/EditForm.aspx?ID={WorkflowVariable:taskID}

You can also set up reminders in your flexi task to run x number of times every x hours/days etc.

Tell your user to navigate the SharePoint site and add a Pending Tasks web part

this is also great - I love making dashboards for users for all their various tasks

Hi All, yes I noticed that we can send out the link manually or set the reminder. but I am finding a way which we can manually trigger it (same as what flexi task trigger with the same email content).

In that case, my first reply would suffice - have a status you can change that will switch a state machine and re-send the FlexiTask.
